[SPAM] Tranny Selection

[scourge at cogeco.ca (Scourge)]

I agree with what most are saying. 4.25 final would be pointless.
I have a 2L ABA w/ a JH head. G-grind cam, dual out manifold, tt race dp.
With the unported head I have some traction issues in first with my 4K.
I opted for a .75 5TH for mine, Just under 3k rpm at 100kph, perfect for my
motor. 4th works it's magic best between 100(~4100rpm) and 140(~5800).

Since you are aiming for more power then I have right now, I'd recomend the
FF you said you have already. It gives you a slightly lower 3.89 final so
you'll manage a little better in 1st. And you should have plenty of power to
deal with the longer 2nd. The .71 5th will give you all you desire on the
highway.
